It's historical -- There was lawsuit between wright vs curtiss. I remember reading wright brothers autobiography and lots of wright brother's books. Wilbur was excellent student in high school, and dream go to college. After his last day of graduation, wilbur played a hockey with someone... And hockey puck smash his mouth and broke few teeths. He couldn't go to college. There was some anger he had.

There was legal battle: Glenn H. Curtiss versus Wright Brothers.

Why don't you read all wrights books? Why do you get those books from EBAY or Amazon or Local Libarary or search engine. Read it...
